The updating isn’t the best right now from my understanding. You will have to re-download the package from the launcher and re-implement it into your particular package. I do believe that is how it works anyways. If any marketplace content creators who have gone through would like to chime in it would be greatly appreciated.
Also I have spoken to other content creators who have made foliage for Unreal Engine 4.6 and lower. The flickering is something that sticks around no matter what but can be reduced to something that is nearly not visible (as seen in the previous 4k video I published). I have already told you the biggest contributors to the problem, but I did leave one out. The cascade settings under your primary light can also be adjusted to minimize the effect if you’re still having the. Once all of those are in full effect as you saw in the previous video the flickering is unnoticeable unless you were to be inches away from the base of the foliage.
